END-GATE FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 363,609, dated May 24,1887.

7 Application filed Novemlger 23, 1886. Serial No. $9.688. (No model.)

My invention relates to an improvement inend-gates for wagons or anydumping apparatus-such as carts, dump-cars for coal or ore, steamshovels, excavators, and dredgers-and has for its object to dump theload by a single movement, and while the apparatus to which it may beattached is in any given position. The object is also to provide adevice which will occupy little space and be permanently attached to theend-gate, whereby the said device will be always at hand when needed.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of my endgate in a locked position, andFig. 2 a partial longitudinal section throughsaid end-gate and lockingdevice. Fig. 3 is a central vertical section through Fig. 1 when thegate is opened, and Fig. 4 is a plan view of the guide-plate.

A represents the side-boards of a wagon, provi ded with cleats a,attached to the inner face thereof,to form grooves a, in which the uppersection, B, of the gate is entered, the said upper section being usuallyfitted with a central vertical brace, B, through an aperture in whichand corresponding apertures in the side-boards A a pin, 1), is passed,to assist in holding the said gate in position and constitute anadditional brace therefor.

A lower section, 0, of a width equal to the height of the openingrequired and of a length equal to the distance between the side-boardsA,is hinged to the upper fixed sections. B, by apertured straps cc,attached to the said sections near their outer edges in such manner asthat the lower apertured end of one and the upper apertured end of theother willregistcr in the same horizontal plane, the hinged connectionbeing effected by passing a rod, D, through through apertures in thesame plane therewith formed in the side-boards A.

The straps c are made to extend the entire width of the lower or hingedsection,O, and are provided near their lower endsat equidistance fromthe bottom with an embossed or struckup portion, d, forming thereby intheir under face a recess, 11.

I attach by screwing or otherwise to the hinged section O,aboutcentrally the same at the bottom,a thin metal p1ate,E,having formedtherein a central aperture, 6, and horizontal slots e ehupon each sideof said aperture e,ex tending through the edges of the plate, as shownin Fig. 4. Horizontal lock-bars F, of a length about equal to half theentire width of the wagon, provided at one end with integralright-angular projections F, are passed through the recesses d in thestraps c, and their outer straight edges enter thimbles D, secured inthe side-boards A,to project usually flush with the outer face of saidside-board, while the angular ends are made to enter, respectively,thehorizontal slots 6 c in the guideplate E.

To operate the lock-bars F, I provide another and thicker plate, H,having a central aperture and cam-slots h h upon each side of saidaperture,and pivot said plate H upon the guide-plate E by a bolt, H,made to pass the said apertured ends of the straps, and also through thecentral apertures of each plate and the hinged gate 0, having first,however, entered the projecting ends F of the lock-bars through thecam-slots h h,where they and the pivot-pin are capped with a suitablenut and washer.

A handle, K, is provided the locking-plate H at the upper portionthereof,which may be made integral therewith or attached thereto, thesaid handle,when the gate is locked,being adapted to engage a spring, K,secured at one end to the gate,purposed to retain the handle in avertical position.

When it is desired to dump a load, the haudle K is simply pulled to theright or left, which action causes the plate H,through the medium of itscam-slots,to withdraw the lockbars F from engagement with the thimblesD, and as the gate is hinged near its extreme upper edge,the pressure ofthe load being from ICO the inside, the gate thereupon flies open andthe load isquickly and handilyunloaded.

The manner in which I hang the gate permits of any desired size ofopening, and the unlocking device, being attached to the gate, is alwaysat hand when needed; again, the device is so simple that nothing isliable to dis order, and by simply withdrawing the pins the entire gatemay be taken out.

My end-gate is equally applicable to all manner of dumping apparatus.

Having thus described my invention, what I claim as new, and desiretosecure by Letters Patent, is

The combination,in an end-gate, with the upper fixed seetiomof the loweroutwardlyswingingsection, the straps c c, secured to th e adjacent edgesof the two sections with their eyes in horizontal alignment, the lowerstraps being bent outwardly to form horizontallyaligncd loops d, the rodD, passed through the sides of the wagon and the'strap-eyes,the plate E,secured to the center of the lower section and formed with twohorizontal slots, e e in alignment with the loops d, the locking-plateH, centrally pivoted to the plate E andhaving eccentric slots h h, andthe locking-bars sliding in the slots Z Z and through the loops (1, andbent outward at their inner ends and entering the slots hh,substantiallyas set forth.
